We've shown you good looking DIY HD antennas and not so good looking ones, but this one, made from a simple disposable pie plate you can get at any grocery store, might look the worst. Even so, it picks up a ton of channels, even from a good distance from a broadcast tower, as you can see in the video above.

Instructables user Tool Using Animal wanted to make the absolute cheapest, simplest HD antenna he possibly could, with whatever materials he had on hand. He snagged a disposable pie plate (seriously, they're usually less than $1 at most grocery stores), a pair of scissors, and a section of coax cable with a connector on the end you'll plug into the TV. He even stripped the coax to connect it directly to the pietenna, although we'd suggest getting something like this $4 matching transformer instead.

Cut out the circular section, attach the cable, hang it on the wall with thumbtacks, plug it into the TV, and go. It's a simple project, perfect for anyone who wants that sweet over-the-air HD but doesn't want to pay for a fancy antenna (or isn't sure they live close enough to get decent reception and wants to test before they buy one.)
